web stream rip software for ripping songs with the highest quality

[any ANONYMOUS forum user]

I need to rip some of those songs for my first short movie.

I tried some web stream rip softwares, but none of them worked; so i need to learn how can i can rip some songs (highest quality) from that flash player from this web page

I need web stream rip softwares for Windows 7 or Vista. Although I have a Mac as well, so if there are better web stream rippers for a Mac, I will accept them.

I appreciate your replies!
